you could but it would prolly be just too much effort.

Can they just bend one up at the muffler shop? Can you just use ordinary stainless steel exhaust piping?

You'll need the piping, flex section, and flanges. you dont have to have the flex but it is recommended. It is a lot of hard work. I would look around to see if you can find local guys who can make it for you. Just make sure it is mandrel bent(not pressbent)

yes it can be done, but weighing the time , and effort to make sure it is a correct fit when finished, it is cheaper and less heartache to buy a prefabed one. But the counter is if you build one... you can have more pride. I would juts buy one, there are plenty on the market.

Yeah I agree with everyone else to much work..just buy one..there are alot of good ones on the market..

Just go get a downpipe that is MANDREL BENT. WHY??? because put it this way.

If you have a straw and you bend it, try sucking the juice out of the glass. It's hard isn't it. Thats how pressbent is.

Now i'm sure you have seen those twisty straws that are made that way (usually you can get them at Chuck E Cheese or something,). When you try sucking out of the twisty, its just like a normal straw. See what I'm trying to say.

Go with Mandrel Bent, it has better airflow.

Pressbent will not give you as good of an airflow.

Hope this helps.

thanks for the input guys. what is the flex part all about? do i really need this? the guy at the shop says he can bend me up a 3" out of stainless steel pipe real easy, and cheap too. I can buy a $300 muffler and still come in at under $500 with all the piping custom bent and installed. i think he has a press bender though. what do u guys think?

Mandrel bent all the way man..so much smoother...also the flex pipe is soemthing to give it the lee way to bend...because the motor flexes back and forth..and the flex section is like a spring..you understand...but yeah I would go with a mandrel bent Downpipe..you can get them for like as cheap as 150 bucks...

Yup Yup, Mandrel all the way. If you can't afford it now, save more ca$h until you do have enough, and go for mandrel. Trust me. Spendin' a little extra cash means you will gain more hp. There are good deals on ebay, so check it out there.
Here's one that I found on ebay.

mine was custom made at a muffler shop, so it wasn't a headache on my part, its 3" O2 eliminator w/ flex. so just find a shop that can do it for you.
(can see it in my gallery)

So are you guys saying if i went with this 3" press bent with no flex section, i won't gain any more power? I can't find any deals on these things. Can i buy a flex piece somewhere? If so, where? If i don't put the flex in, can i screw up my car? I have no idea about this stuff, ur guys opinions really help. You know, i don't, so thanks for your help.

well the downpipe is bolted on the turbo, and the turbo is bolted onto the engine, and the engine moves alot. you dont want the engine slamming the exhaust around under the car. thats why there's a flex

What we are telling you is buy an already built downpipe with flex section. IT IS NOT WORTH IT BUILDING YOUR OWN.

here si what a DP with flex looks like.

i had a 2.5" straight piped press bent cat back done by my uncles friend for $300 including giant muffler tip. as for a downpipe, you can get a 3" aluminized steel DP for under $200. having one made wouldn't really be worth it, unless you are going for the whole DIY eclipse, in which, have at it
